I bought a "Baby Betta" not too long ago! They're very fun to take care of, but you have to be responsible and diligent! I fed her 3-4 of these pellets a day along with blood worms I chopped up: http://www.petco.com/product/104065/...at=BettaHPFood
If you take good care of them, they turn out beautifully! When I got Poppy she as only the length of my thumbnail, but now she's HUGE! I mean, her tail is the biggest I've ever seen in just a regular veil tail female! She's adorable and I've grown so attached to her!
I haven't gotten a good picture of her yet because she just doesn't stay still!! Anyways, this photo shows how big her tail fin is :) <3
